drop statpack automatation job.

Hi,

I wrote below PL/SQL to remove exising dbms_job from database, which was configured by spauto.sql script. but it giving error "invalid SQL"

set serveroutput on;

DECLARE

cursor c1 is SELECT DISTINCT job FROM dba_jobs WHERE what='statspack.snap;';

jnumber c1%rowtype;

sqmt  varchar2(100);

BEGIN

open c1;

loop

fetch c1 into jnumber;

EXIT WHEN c1%NOTFOUND;

sqmt := 'EXECUTE DBMS_JOB.REMOVE(' || jnumber.job || ');';

execute immediate sqmt;

end loop;

close c1;

commit;

dbms_output.put_line('Statpack JOBS remove sucessfully');

END;
